I thought it was removed when the parent process acknowledges the
process end via the wait() function.

Yes, but vdr does not wait() for the kernel thread...
It doesn't even know that a kernel thread has been created. Therefore, the cleanup will be performed when vdr exits.

..., unless the kernel thread is reparent'ed to init, which will care about terminated threads. This is not done automatically by daemonize(), but may be done by the function reparent_to_init(void) (exists in kernel versions 2.4 and above), to be called just after daemonize(). This subject has already been discussed elsewhere, see :
